}

when i use the scanf command i get the same information that i send (the AT command) if use the GetData() the program crash out. why??? what must i change to read a message from gsm???
(the connection between gsm and stk is why null modem cable (2 females) and i connect the 2,3,5 pins from cable to 3,2,5 on avr the same connection is on modem)

please help me because time pressure me and i don't know what to do...

i hope to your answer...
